Ajouter au panierNew York, American Telephone and Telegraph Company, 1946. 8vo. Volume XXV, Number 2, April 1946 of "The Bell System Technical Journal". Entire volume offered. In the original printed blue wrappers. With previous owner's name to front wrapper. Sunning to spine and margins of front wrapper. Back wrapper loose. An overall nice and…clean copy. Pp. (4), 167-349. First printing of Bell Labs Magnetron issue. The Magnetron is a high-powered vacuum tube that through a stream of electrons in a magnetic field generates microwaves. This reduced the size of radar sets which made it possible to install them in anti-submarine aircrafts and escort ships. This had a profound influence on the warfare during WWII. Today magnetrons are commonly used in microwave ovens and in various radar applications."The studies of Fisk, H. D. Hagstrum, and P. L. Hartman [the present paper] increased the understanding of the role that the various possible modes of oscillation played in magnetron operation and the effect of the wire straps - which later evolved into two pair of concentric copper rings." (Millman, S. A History of Engineering & Science in the Bell System, 1984, p. 173).
